- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 155.47 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point of the test item was determined to be 155.47 ± 0.06 ºC.
- Executive summary:
A differential scanning calorimetry test (DSC) was performed to determine the melting point of the test item. Around 5 mg of test item were weighed in non-hermetic aluminium capsules and studied by differential scanning calorimetry over a temperature range extending from T = 293.15 K to the melting point temperature of the sample, with a heating rate of 1 K/min. All determinations were performed in a dry-nitrogen atmosphere. Based on the test results, the melting point of the test item is 155.47 ± 0.06 ºC.
